Site-specific daily scenarios for maximum and minimum temperatures, precipitation, humidity. SDSM
also produces a range of statistical parameters such as variances, frequencies of extremes, spell
lengths.

Key Input

Quality observed daily data for both local-scale and large-scale climate variables to calibrate and
validate the statistical model(s). Daily GCM outputs for large-scale variables for future climate to
drive the model(s). The current version (4.2) contains observed data libraries for use in model
calibration, and GCM data for making future projections.

Ease of Use

The user-friendly software is largely self explanatory. It comes with comprehensive instructions for
use.

Training Required

Requires little training for those familiar with climate science but it requires expert knowledge and
reiterated efforts to establish realistic and accurate statistical relationships.

Training Available

There are currently no plans for any training courses

Computer Requirements

SDSM 4.2 has been tested on the following minimum specifications: PC Windows 98/NT/2000/XP (it may
also work on Windows 95 but has not been tested on this OS); Memory - 5 MB RAM, 48 MB ROM; Processor
- 133 MHz; Coding language - Visual Basic 6.0. Note: for older machines SDSM may work but may
crash or take longer to perform certain analyses when large data sets are processed.
